Abstract
Extensible Markup Language (XML) is playing an increasing important role in web services and database systems. However, the task of XML parsing is often the bottleneck, and as a result, the target of acceleration using custom hardware or multicore CPUs. In this paper, we detail the design of the first complete field programmable gate array (FPGA) accelerator capable of XML well-formed checking, schema validation, and tree construction at a throughput of 1 cycle per byte (CPB). This is a significant advancement from 40 CPB, the best previous reported commercial result. We demonstrate our design on a Xilinx Virtex-5 board, which successfully saturates a 1 Gbps Ethernet link.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
